3" Duct Line Dart (Yellow)

Series 58300 Birds feature tapered cones, providing better flexibility for blowing around bends. The thin flared edges offer better sealing capabilities with increased speed when blowing under pressure. Cones are color coded to correspond with the 58200 Duct Seal Kits (sold separately) and replacement cones are available too. This 58300-300 yellow line dart is designed for blowing through 3-inch empty ducting.
